Because i'm cheap
 

So i was thinking about wearing some base layer stuff and then a light shell jacket its waterproof but not thick enough and then a sweatshirt to a mountain. Is that good or should i go with a jacket? I would probably be going in the east coast if that helps.

do you think i should do both? or just a jacket?

TJMAX is a good one to

What are the temps like where you ride? You could probably just layer a shell if it's around 20-30. I ride a lightly insulated shell and it does well for me.

ya im not riding in too cold weather i think i may do both i have a jacket i dont use too much but its ok. I might buy some hoodies for when its warmer too

tjmaxx is legit. and a sweatshirt with good layers beneath (like a tshirt and long sleeve shirt) will be plenty warm with a water resistant shell that will also block out wind. and can be very comfy if you fit em right

go to ebay or craig's list and you can find a good quality jacket (name brand if you want) for under a hundred dollars. it's what i did, and will continue doing seeing as i keep finding holes in my wallet. this economy is sucking everyone dry....

or just watch brociety or tramdock always good deals

Don't use a cotton sweatshirt. Get something that is synthetic. Using a shell and layers is fine otherwise.

What kind of base layers are you going to wear? To me the first layer makes all the difference in the world, I would Highly recommend getting on of those underArmor cold gear mock neck tight base layers, if you want to save some $ try one on in the store to get the size and model then buy it on ebay or something. but I wouldnt skimp on your warmth. yea you dont have to get the most expensive jacket, but these underarmors make a hell of a difference. I ride out east and all I wear is that base layer and my shell jacket most of the time if it gets real cold then I throw a cheap fleese on as well and Im never cold.
